IGNITION SYSTEM
THROTTLE OVERRIDE SYSTEM (T.O.R.S.)
If the carburetor or throttle cable should malfunction
during operation, T.O.R.S. will operate when the
throttle lever is released.
T.O.R.S. is designed to interrupt the ignition and
keep the engine revolutions between 2,800 and
3,000 r/min if the carburetor fails to return to idle
when the lever is released.
WARNING
• If T.O.R.S. operates, make sure that the cause
of the malfunction is corrected and that the
engine can be operated without a problem
before restarting the engine.
• Be sure to use the standard resistance-type
spark plug and ignition coil. Otherwise,
T.O.R.S. will not work properly.
